Cube the sourdough bread into bite-sized pieces, about 1-inch cubes, the place them in a large bowl and set to the side.
For this recipe, you can use a fresh or slightly stale loaf of my Beginner's Sourdough Bread. Sometimes I will remove really tough pieces of the crust.
1/2 loaf of sourdough bread
In a separate bowl whisk together the eggs, milk, heavy cream, maple syrup, vanilla extract, remaining 1 gram (1/2 teaspoon) of ground cinnamon and salt until combined.
200 grams large eggs,240 grams milk,60 grams heavy cream,65 grams maple syrup,4 grams vanilla extract,3 grams salt
Grease a 2.5 QT baking dish with nonstick cooking spray.
Place half of the bread into the prepared baking dish and top that layer with half of the cinnamon apple mixture and cubed cream cheese. Top that layer with the remaining bread cubes and cinnamon apples.
110 grams cream cheese, cubed into small pieces
Next, pour the custard mixture over the into the prepared casserole dish. Allow the casserole to rest for 30 minutes.
This allows the bread to soak up the custard prior to baking. and place it into the preheated oven.
While the casserole rests, preheat the oven to 350 degrees F.
After 30 minutes, place the casserole in the hot oven and bake for 50-55 minutes, or until the middle is cooked through with no more liquids and the top of the casserole is golden brown and slightly crisp.
Serve immediately with powdered sugar and a drizzle of maple syrup on top!
